The Controversy Over Super Wool By Nicholas Antongiavanni From the May/June 2007 Issue Filed under: Lifestyle, Culture, Science & Technology Better sheep-breeding techniques and advances in loom technology have made the cloth that goes into men’s suits finer and softer. But, Nicholas Antongiavanni asks, are the suits really better? In the fitting room of a Manhattan depart ment store, a partner in an expensive New York law firm looks uneasily in the mirror. His new made-to-measure suit does not seem to fit quite cor rectly. He has brought along a younger associate to render an opinion. The boss may be richer and a more experienced litigator, but his confidence fails him when he ...

Spray-On Solar-Power Cells Are True Breakthrough Click here to find out more! Stefan Lovgren for National Geographic News January 14, 2005 Scientists have invented a plastic solar cell that can turn the sun's power into electrical energy, even on a cloudy day. The plastic material uses nanotechnology and contains the first solar cells able to harness the sun's invisible, infrared rays. The breakthrough has led theorists to predict that plastic solar cells could one day become five times more efficient than current solar cell technology.

NEW YORK The desire for greater control over how search engines index and display Web sites is driving an effort by leading news organizations and other publishers to revise a 13-year-old technology for restricting access. Currently, Google Inc., Yahoo Inc. and other top search companies voluntarily respect a Web site's wishes as declared in a text file known as "robots.txt," which a search engine's indexing software, called a crawler, knows to look for on a site. The formal rules allow a site to block indexing of individual Web pages, specific directories or the entire site, though some search engines have added their own commands. The new proposal, to be unveiled ...

The Sliding Rocks of Racetrack Playa
One of the most interesting mysteries of Death Valley National Park is the sliding rocks at Racetrack Playa (a playa is a dry lake bed). These rocks can be found on the floor of the playa with long trails behind them. Somehow these rocks slide across the playa, cutting a furrow in the sediment as they move.
Some of these rocks weigh several hundred pounds. That makes the question: "How do they move?" a very challenging one.
The truth: No one knows for sure exactly how these rocks move - although a few people have come up with some pretty good explanations. The reason why their movement remains a mystery: No one has ever seen them ...

Has first evidence of another universe been seen? By William Atkins Astronomers announced in August 2007 the discovery of a large hole at the edge of our universe. Since then, theoretical physicist and cosmologist Laura Mersini-Houghton and colleagues have claimed it is an “unmistakable imprint of another universe beyond the edge of our own.” The article entitled “Astronomers Find Enormous Hole in the Universe” discusses the August 2007 discovery of the hole. It is located at the National Radio Astronomy Observatory website. Dr. Laura Mersini-Houghton is a theoretical physicist and cosmologist at the University of North Carolina (Chapel Hill). The hole is ...

Diggers leave digg for Mixx (Weekend Wrap-up Nov 25) Pandia takes a look a this week’s search engine headlines and presents Mixx, a newcomer to the social web scene. Techcrunch reports that many contributors to the social web “submit-and-vote-for-articles” site digg are frustrated with the current culture and practices. Many of them are therefore looking for a new home on the Web. Some go to propeller (previously known as the Netscape home page), others to reddit — both useful tools for following current news and blog trends. Others are going to a new social web sites called Mixx. Mixx is, indeed, very similar to digg, and focuses on submissions of — and ...

Astronomers discover stars with carbon atmospheres PRESS RELEASE Date Released: Wednesday, November 21, 2007 Source: University of Arizona Astronomers have discovered white dwarf stars with pure carbon atmospheres. These stars possibly evolved in a sequence astronomers didn't know before. They may have evolved from stars that are not quite massive enough to explode as supernovae but are just on the borderline. All but the most massive two or three percent of stars eventually die as white dwarfs rather than explode as supernovae. When a star burns helium, it leaves "ashes" of carbon and oxygen. When its nuclear fuel is exhausted, the star then dies as a white dwarf, which ...

Mankind 'shortening the universe's life' By Roger Highfield, Science Editor Last Updated: 12:01am GMT 21/11/2007 Forget about the threat that mankind poses to the Earth: our activities may be shortening the life of the universe too. The startling claim is made by a pair of American cosmologists investigating the consequences for the cosmos of quantum theory, the most successful theory we have. Over the past few years, cosmologists have taken this powerful theory of what happens at the level of subatomic particles and tried to extend it to understand the universe, since it began in the subatomic realm during the Big Bang. But there is an odd feature of the theory that ...

A shape could describe the cosmos and all it contains ONE of the mysteries of the universe is why it should speak the language of mathematics. Numbers and the relationships between them are, after all, just abstract reasoning. Yet mathematics has shown itself to be particularly adept at describing both the contents of the universe and the forces that act on them. Now comes a paper which argues that one branch of the subject—geometry—could form the basis of all the laws of physics. Physicists are an overbearing bunch. They have long sought a “theory of everything”. Such an opus would unite the fundamental forces—gravity, electromagnetism and the two forces that ...

Robo-Moth: UA robot driven by moth's brain. Charles M. Higgins, UA associate professor of electrical and computer engineering, and doctoral student Timothy Melano presented their findings and outlined the mechanics behind the robot’s movements. The robot’s motion is guided by a tiny electrode implanted in the moth’s brain, Higgins said, specifically to a single neuron that is responsible for keeping the moth’s vision steady during flight. The neuron transmits electrical signals which are then amplified in the robot's base and through a mathematical formula, a computer translates the signals into action, making the robot move. The moth is immobilize inside a ...

Innovation? How About Just Taking Out the Trash? Tony Long 11.22.07 | 12:00 AM The tech industry -- makers of hardware, software and every ware in between -- prides itself on innovation. If George Bush is the decider, then Steve Jobs and his pals, er, rivals at Dell and IBM are the innovators, the geniuses, the gurus. We’ve elevated these guys to rock-star status, which I suppose makes sense, because they provide the tools that allow a self-involved culture to wallow in its narcissism. They keep us kitted out with must-have laptops and iPods and Blackberries, thereby giving us texting and virtual worlds and, hoo-wahhh, our own personal music. Unfortunately, all these way-cool ...

Global Warming Consensus Does Not Exist Among Scientists Letter to the editor: The Wichita Eagle Written By: Joesph Bast Published In: Heartland Perspectives Publication Date: September 5, 2007 Publisher: The Heartland Institute Randy Scholfield in his August 24 column (“Why do some deny global warming?”) wonders why so many people “resist the evidence of human-caused climate change.” After all, he writes, “the overwhelming consensus of mainstream science is clear.” Scholfield is deeply confused about the subject, but it isn’t his fault. Media coverage of global warming confusing, and too many scientists have made careers out of issuing scaring ...

Battle of the Nobel climate horror disaster movies Terence Corcoran, Financial Post Published: Tuesday, November 20, 2007 So here's our ethical predicament for today: Is it wrong to be a shouting scaremonger in a crowded movie theatre full of shouting scaremongers? And, one might ask, what happens when a scaremonger shouts fire in a theatre full of people shouting fire? The answer to the second question is easy: Nothing. That's what happened last Saturday, when the Nobel Prizewinning United Nations panel on climate change, in another of its patented panic-inducing document dumps, told the world that the end is near. Unless we all rush for the exits and bring on a massive ...

Are We There Yet?

Are We There Yet? (October 5, 2007) Many people ask if we are at solar minimum yet and how do we know when we are. Solar minimum is the period when the Sun has reached its lowest point of solar activity in its 11-year cycle. One way to see if we are there yet is to observe the solar corona, easily seen in SOHO's C2 coronograph images. The structure we see in the coronagraph images is a marker for the global magnetic field extending into the corona and heliosphere. When the Sun is at its minimum and the corona is "relaxed", the elongated structures in the corona will extend out horizontally with both sides fairly balanced. See the bottom coronagraph from 1996. At solar ...

NASA Sees Arctic Ocean Circulation Do an About-Face PRESS RELEASE Date Released: Tuesday, November 13, 2007 PASADENA, Calif. A team of NASA and university scientists has detected an ongoing reversal in Arctic Ocean circulation triggered by atmospheric circulation changes that vary on decade-long time scales. The results suggest not all the large changes seen in Arctic climate in recent years are a result of long-term trends associated with global warming. The team, led by James Morison of the University of Washington's Polar Science Center Applied Physics Laboratory, Seattle, used data from an Earth-observing satellite and from deep-sea pressure gauges to monitor Arctic Ocean ...
